WAVE-MOTOR.

Specification of Letters Patent.

Patented Sept. 13, 1910.

Application filed February 21, 1910. Serial No. 545,191.

To all whom it may concern:

Be it known that I, WILLIAM L. RAIIT, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented certain new and useful Improvements in Wave-Motors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable those skilled in the art to which it appertains to make and use the same.

My invention relates to wave motors of such construction, the larger portion of which is on shore and the objects are to provide a wave motor that will not wash out or be destroyed in storms and that the energy produced by the undulations of the water is stored by means of an air or water pump, pumping into a reservoir.

The invention consists in the features of construction hereinafter fully described and specifically claimed.

In the accompanying drawing forming a part of this specification, Figure 1 is a side elevational view of the mechanism with a sectional view of the air or water pump and Fig. 2 is a detail of the top or fulcrum piece of the main supporting post.

Similar characters of reference refer to similar parts throughout the several views.

The main supporting post 1, lever 2, float 3, air or Water pump 4, weights 5 and 6 constitute the principal parts of my invention. The main supporting post 1 is preferably, a round column but may be a structural steel tower and is thoroughly embedded in the ground, on the shore in a substantial manner and in such a place that it will not be sub-. jected to wash from the waves. I have provided a plurality of guy wires 1 which are attached near the top of said post their lower ends being thoroughly anchored to the ground some distance from said post by means of stakes 1 driven in the ground for that purpose, in each of said guy wires is provided a turn-buckle 1 for the purpose of tightening said wires to the desired tension. On the top end of said post 1 is provided a double fulcrum piece 1 as shown best in Fig. 2 which is provided with the bolt 1 on which is pivoted a long lever 2 with the greater portion of its length extending out over the water. To said extended end is attached a cable 6 which in turn extends downward and is attached to an eye-bolt extending through a large float 3 and attached thereto, said float 3 is made of suitable material and adapted to float in the water, being partially submerged. On the top of said float and on said eye-bolt is provided a plurality of weights which may be added to or taken from for the purpose of properly adjusting the weight of said float, the inner and short end of said lever 2 is provided with a segment 2 concentric with the pivot point on said lever and on the top edge of said segment at 2 is substantially attached cable 7 which is adapted to bear on said segment 2, directly beneath the inner portion of said segment is provided an air or water pump 1 substantially attached to the ground, and which is provided with a piston 1 to which cable 7 is attached, said cable being provided with a plurality of weights (5 which may be added to or taken from so as to provide sufficient weights to operate said pump 1 on its downward and active portion of its operation. From said pump is provided a pipe adapted to convey the air or water to a reservoir, adapted for the storage of said air or water.

It will be readily seen from the foregoing description that, owing to the undulations of the water, float 3, will rise and fall and by means of the lever and cables wit-h their weights will raise and lower the piston 41 which will force the fluid which may be air or water in to a reservoir where it can be stored under compression, and may be used as it accumulates as is most convenient.

The manner in which the fluid is used after leaving the pump does not form a part of the invention and can be carried out in any manner desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A wave motor, comprising a main supporting post mounted upon the shore, provided with a plurality of adjustable guy wires, a fulcrum piece mounted on said post, a lever pivotally mounted on said fulcrum piece, one end of said lever extending over the water and being of greater length than the inward ext-ending end, a cable attached to the long end, a float attached to said cable, detachable weights adapted to change the weight of said float, a cable attached to the upper portion of the short end of said lever, an air or water pump in connection with said cable, detachable weights adapted to operate said pump piston in one direction and a service pipe in connection with said pump all substantially as set forth.

2. A wave motor, comprising, a main supporting post, guy wires to said post, turnbuckles in said guy wires all substantially anchored on the shore near the waters edge, a lever with extending ends pivotally mounted on said posts, the longer end extending over said water, a cable mounted on said extended end, a float adapted to float in the water, provided with an eyebolt and with detachable weights attached to the lower extended end of said cable, the inner and short end of said lever provided with a segment concentric with its pivot point, a cable attached to the upper portion of said segment and to its lower extended end, a pump piston, a pump cylinder in conneotion with said piston, detachable weights in connection with said piston and a service pipe from said pump all substantially as set forth.

In testimony whereof I hereunto subscribe my name in the presence of two subscribing witnesses.

WILLIAM L. RAHT.
